iOS map-type data structure?

[xytor]

Does NSFoundation have a data structure like the std::map? NSMutableDictionary is close, but doesn't seem to have any way to check if a certain key is already inside.

NSDictionary is it. objectForKey: tells you if there's an object stored with the specified key.

That's excellent, but how come the documentation makes no mention of this function?

Is there any documentation that lists ALL the functions?

Thanks.

Because Apple do not duplicate the documentation from superclasses in subclasses. The objectForKey: method (not function) is defined in NSDictionary which is NSMutableDictionaries superclass. So any NSDictionary method can be called on a NSMutableDictionary.

Ooh that's good. My bad. Thanks for the clarification!
